Actually it may have been something I did.  I have a sound clip I cut and had it as the start up sound.  It's Dr Evil's speech on sharks with freakin' laser beems attached to their heads.  But I cut out Sea Bass and inserted "Welcome to Windows 98".  Just seemed to fit better.  Oh well, I went with something shorter and so far It's seemed to stop the problem at least until the next time I turn it on.
